I wash everything except jelly rolls and charm packs, too. I have also bought several kits from Craftsy. Craftsy has exceptional customer service and, thus, is really good about replacing any cuts that are too short. I have washed every fabric that I have gotten in their kits and have never had to ask for a replacement. There won't be a lot of excess though, so plan your cuts. On the other hand, I know others that have received fabric that was cut too small. Those quilters have never had an issue with Craftsy sending out more fabric. Therefore, I would wash them in cold water and dry them on low. Then if there is an issue once you start cutting, contact Craftsy.
